Symfony2 Choice Form Data from ORM - symfony

Question

Have this form:
class ScanType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('scantarget', 'entity', array(
'class' => 'AppBundle:Website',
'property' => 'url'
));
}
public function getDefaultOptions(array $options) {
return array(
'data_class' => 'AppBundle\Entity\Website',
);
}
}
Need to populate it with only urls for the particular userid
In the controller:
/**
* #Route("/verification-ok", name="verifyurlok")
*/
public function verifyurlActionOK(Request $request)
{
$user = $this->getUser();
if($user)
{
$userid=$user->getId();
$websites = $this->getDoctrine()->getRepository('AppBundle:Website')->findByUser($userid);
$form = $this->createForm(ScanType::class, $websites);
However, the $websites is not passed properly to FormBuilder and in my Select box I see all entries :( All possible values for Website entity.
How to Display only passed $websites in the form (select box)? So only websites for a specific userid?
Thanks,

config.yml
services:
app.form.scan:

arguments: ['#security.token_storage']
tags:

Unfortunately, get this error:

Form:

use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Symfony\Component\Form\Extension\Core\Type\EmailType;

$builder->add('scantarget', 'entity', array(

}
public function setDefaultOptions(OptionsResolverInterface $resolver)

}
}
Controller:
$form = $this->createForm(ScanType::class, $websites, array(

));
Works!!!

Answer 1

Well, you are not setting the choices. Try this:
class ScanType extends AbstractType
{
private $websites;
public function buildForm(FormBuilderInterface $builder, array $options)
{
$this->websites = $options['trait_choices'];
$builder->add('scantarget', 'entity', array(
'class' => 'AppBundle:Website',
'property' => 'url',
'choices' => $this->websites
));
}
public function setDefaultOptions(array $options) {
return array(
'data_class' => 'AppBundle\Entity\Website',
'trait_choices' => null,
);
}
}
In the controller pass through the websites:
$form = $this->createForm(ScanType::class, $websites, array(
'trait_choices' => $websites,
));

Answer 2

Your form displays all the Website entries because you're not restricting them when building the form, in the add() method.
You should read this section fo the cookbook : http://symfony.com/doc/current/form/dynamic_form_modification.html#form-events-user-data
